NAME

Cell growth

DESCRIPTION

Cell growth usually refers to cell proliferation, the increase in cell numbers that occurs through repeated cell division. Cell growth can also refer to the enlargement of cell volume, which can take place in the absence of cell division.

Cell biology is the discipline of biological sciences that studies the structure, physiology, growth, reproduction and death of cells. Research in cell biology uses microscopic and molecular tools and examines all cell types, from unicellular organisms such as protozoa to the specialised cells that consitutute multicellular organisms.

Cell division is the process by which a parental cell gives rise to two daughter cells. The process involves both nuclear division and cytokinesis and can either produce two equal cells (symmetric cell division) or two cells with different cellular fates (asymmetric cell division).

Developmental biology is the field of biology that studies the processes by which multicellular organisms grow and develop, controlled by their genes. Knowledge of normal developmental processes can aid in the understanding of developmental abnormalities and other conditions such as cancer.

Hippo signalling is a cell signalling pathway that controls organ size. Activation of Hippo results in a series of phosphorylation events that culminate in the phosphorylation and cytoplasmic retention of a downstream transcriptional coactivator, terminating expression of Hippo-regulated genes. Hippo signalling has an important role in development and cancer.
